'16 Claims.

My invention relates to spinning frames.

It has among its objects to provide improved means for controlling anddirecting the drafted ends. A further object is to provide such improvedmeans especially adapted to use in connection with pressure mechanism ofthe type whereby the twisting of the yarn is divorced from the draftingfunction of the front rolls. Another object of my invention is toprovide such improved means adapted to be carried on a concave pressureplate of such a mechanism and which, while in no way interfering withthe operation of the latter, also functions to improve the endcontrolling-function of such a plate in such manner as with increasedcertainty to cause any end resulting from breakage of the yarn to bedirected upward and lapped around the top front roll fromwhich it may bereadily removed. Still further objects'of my invention .are to providean improved lap maker adapted to catch a drafted end escaping from aconcave pressure plate and control and direct said end in an improvedmanner, and, more particularly, to provide such an improved lap makeradapted to form an extension of sucha plate and to be carried'thereon.These and other objects and advantages of my improvement will, however,hereinafter more fully appear;

In the accompanying drawing, I have shown for purposes of illustrationtwo embodiments which my invention may assume in practice.

In this drawing:

Figure l is an end elevation of a spinning frame equipped with myimprovements;

Fig. 2 is a front elevation of a portion of the frame;

Fig. 3 is a sectional view on line 3-3 of ure 1;

Fig. 4 is an enlarged end elevation of my improved structure inoperative position Fig. 5 is an enlarged plan view of the same asseen online 5-5 of Figure l;

Fig. 6 is a detail perspective View showing connection of the lap makerto the supporting plate of Figure 4, and

Fig. 7 is a view similar to Figure 4, of a modifled construction.

As illustrated herein, a standard form of spinning frame is shownincluding a usual carriage stand 5 having usualdraftingmechanism'including-a'lower fluted front roll 2 and a suitable top frontroll 3, herein cork covered, while a usual ressure framed carriesresilient'pressure means 5 on'its front end and is pivoted at B on thefront saddle bar I my improved lap maker mechanism,

generally indicated at 8, being carried by the pressure means 5 andcooperating therewith and with the top front roll 3 in an improvedmanner as hereinafter described.

The pressure means 5 shown herein is of the resilient type invented byWalter S. Eastman, and is not per se the subject matter of my presentinvention. However, to facilitate understanding of the latter, it isdesirable to note that this pressure means includes a supporting plate 9having a central hole therein adapted to receive and be seated on anupstanding ball II} on the front end of the pressure frame 4 'toprovidea universal joint, while an upper resilient pressure plate H hasdepending edges 12 receiving and supporting the plate 9, and upturnedends It on the latter support the pressure plate I3 at the oppositeends, as usual in such devices. Thus, the drafted yarn passing outbetween the nip of the drafting rolls Zand 3 is supported on the plateH, which, when pressed upward by the pressure frame 6, is flexed andconforms to'the bottom of the top roll 3 while the twisting begins afterthe yarn is free from pressure and as it passes off the enlarged frontedge i2 of the plate ll downward to a usual closed pigtail guide I4disposed above the caps [5 of usual whirl bobbins Hi, all in the mannerusual in such Eastman devices. I

In my improved construction, the supporting member 9 carries my improvedlap maker mechanism fl. As shown, the latter includes an elongated bodyll of substantially the width of the roll 3 and of the supporting member-9 and transversely shallowly corrugated while conforming generally tothe periphery of the top roll 3. Herein, the inner edge l8 of thismember is parallel to and spaced in front of the enlarged curved frontedge of the-pressurepla'te II. To maintain this relation while stillproviding for the support of the 'member II on the supporting member 9,a laterally and longitudinally disposed fiat extension 19 is provided onthe memher I! adjacent its edge [8 and the free end of this extension isextended laterally in parallel spaced relation to the edge IS. A portion20 is accordingly provided which is adapted to overlie the plate '9adjacent the front upward extension l3 thereon and to be suitably fixedto the plate 9 as, for example, by rivets 2 i Thus, without interferingwith the operation of the pressure plate II, the member I1 is supportedinthe desired spaced relation and caused to be disposed with itscorrugated surface forming an extension of the pressure plate II andextending a substantial distance beyond the latter upward and around theroll 3 in proximity thereto and generally conforming to the peripherythereof, al-

though in spaced relation from the latter.

rugations into contact with the periphery of the" roll 3, or caused tobunch in the space between the member I! and the roll 3 until the lattercan engage a portion of the bunched yarn and start to lap the samearound the roll. Obviously this lapping, once started, will continue andthe lapped yarn may be readily removed by the op erator. t V v As aresult of my improvement, it is found that the troubles heretoforeexperienced when an end does break and get away from the concave plateH, and shoot out of the same into the alley or cross over to the nextend'in such manner as thereby to cause more broken ends, are effectuallyovercome. Further, it will be noted that this mechanism maybe applied tothe pressure mechanism with facility, and that the same is inexpensiveand does not in any way interfere with the normal operation of thepressure mechanism. Also, it willbe evidentthat my improvement iscapable of being applied to other forms of pressure mechanism of theEastman type than that illustrated in'- Figures 1 to 6, the same, forexample, also being shown in Figure '7 as applied without-change to sucha mechanism having a rigid concave plate 22. a

'While I-have in this application specifically described two embodimentswhich my invention including a pressure plate conforming to the topfront roll, and lap maker means carried by said may assume in practice,it will be understood that the same are shown for purposes ofillustration, and that the invention maybe modified and embodied invarious other forms without departing from its spirit or the scope ofthe appended claims. f What I claim as new and desire to secure byLetters Patent is: i
